PUMPING JACK.

Application filed March 17, 1927. Serial No. 176,031.

Pumping jacks as heretofore used ordinarily involve an oscillating ack to which pull rods are attached, the movement of the jack being communicated to the pump for pumping the well. Where deep wells are used the weight of the parts seriously affects the as follows Fig. 1 shows a side elevation of the pumping jack.

Fig. 2 a section on the line 22 in Fig. 1.

1 marks the base of the jack, 2 the standing post, 3 the walking beam, 4 the polish rod, 5 the pivotal mounting for the polish rod on the walking beam, 6 the gland, and 7 the easing to which ordinarily the horizontal member is secured. Braces 8 extend from the post 2 to the base 1 thus bracing the post.

The jack proper has the horizontal menr her 9 which has one end connected through a pitman 10 with the walking beam 3. The horizontal member is mounted on the usual saddle 1-1. A vertical member 12 is fixed on the end of the horizontal member and prete1=- ity. Acounterbalance extension 15 is formed of bars corresponding to the bars making up the ho *izontal member 9. These bars are arranged each side of the vertical. member 12, the inner ends overlapping the horizontal A clamping bolt 16 extends through the bars forming the counterbalance extension clamping them against the vertical member 12. A plate 17 is arranged under the horizontal members 9. A similar plate 18 is arranged over the ends of the bars forming the counterbalance extension 15 and a bolt 19 extends through the plates and between the bars, thus securing. the overlapping end of the counterbalance extension to the horizontal member of the jack. -These extending bars are further secured together by bolts 20. These double bars form a convenient means for receiving the counterweight, such as 21, and may be very simply applied to give'great strength. They permit of the use of any convenient weight particularly round tools which are usually scrapped from the operating, or drilling of oil wells.

What I claim as new is 2- 1. In a pumping jack, the combination of a frame comprising a horizontal rocking member and a vertical member fixed therewith; a saddle on which the jack oscillates; means connecting the jack with a pumping rod; a counterbalance extension opposite the horizontal member, said horizontal member being formed of parallel bars and the counterbalance extension comprising parallel bars above and overlapping the bars .of the horizontal. member; and means securing the overlapping bars of the counterbalance extension to the horizontal member.

In testimony whereof I have hereunto set my hand.
